IMPROVED REVOLVING EXTENSION-COLTER AND GAGE-WHEEL COMBINED.

Specification forming part of Letters Putent'No. 3%065, dated December 2, 1862.

To all whom it may concern.-

Be it known that I, W. H. XVILLARD, of Cleveland, in thecounty of Ouyahoga and State of Ohio, have invented new and useful Improvements in Combined Extension Revolving (Jolter and Gage-VVheel for Flows; and I do hereby declare that the following is a full and complete description of the construction and operation of the same, reference being bad to the accompanying drawings, making part of this specification, in which- Figure l is a side view, Fig.2 is a front view, and Fig. 3 is a sectional view, of the wheel showing the eXtension-colters.

Like letters refer to like parts in the several views.

The points of novelty in this improvement consist in combining a revolving extensioncolter with a gage-wheel, to be attached to the beam of plows in the usual manner.

A is the plow-beam.

B is an arm, which is secured to the plowbeam in such a manner, by means of the cap G and set-screw C, that it can be adjusted vertically.

Dis an axle, upon which the wheel E revolves. Thus far the arrangement is similar to the ordinary gage-wheel on plows. The rim E of the ing extension colters Gr, Fig. 3, (shown also in Fig.1, but not extended,) consist of four steel plates with slots '2', that slide upon the bar of the bolts 0, so that the colters G can be extended beyond the circumference of the wheelE one, two, or three inches; or different sets of blades may be made which extend to any desired distance beyond the face of the wheel. These seg' mental blades G are secured in any desired position, as seen by the dotted lines in Fig. 3, by screwing up the nuts on the bolts 6, and thus clamping the segments between the two portions of the rim E F. hen the blades are drawn in even with the face of the wheel the wheel simply acts asa gage-wheel for the plow.

In breaking up sward-ground, where a colter is needed, the blades G are extended, as seen in Fig. 3, to the desired extent and secured as above stated. The segments G may be so constructed, as regards length, as to form a continuous blade without openings between the segments.

The advantages of this form of colter are twofold: First, it takes less draft than the stationary one; second, where stalks or stubble lie upon the ground a line of separation is made withoutclogging, and the stubble is thus turned under and neatly covered.

What I claim as myimprovement,a1id desire to secure by Letters Patent, is-- A gage-wheel and revolving extension colter constructed and operating substantially as and for the purpose specified.

H. WILLARD.
